This will help people remember what waste to put in which bin,” said Bijin Krishna, the commissioner of the Howrah Municipal Corporation (HMC).
Krishna said ward 22, where the waste segregation scheme has been introduced, has a population of 24,000.
The UNDP is also helping the civic body raise awareness on the necessity of waste segregation.
Waste segregation at source is practised only in handful of places in Bengal.
Howrah Municipal Corporation officials said they had plans to expand waste segregation at source across the entire municipal area.
